I've got five of these defective lowers.
5/5 I can't get any mag in (Magpul Gen2, Gen3, 10,20, 30... Troy Battle Mag, GI Mag). If I get it in, it surely doesn't come out.
How did you get Paul's number? How long did it take to get new ones?

Thanks greg

Greg, I had the same issue with the two shadow ops lowers I received about a month ago. I ended up finding my loosest fitting GI mag and spreading lapping compound on the edges that rubbed the lower. Twenty minutes of working the clip in and out and the fit loosened up. It seems as though the mag well tolerances are tight enough that the anodizing process adds just enough to make mag fit undesirable. Once I was finished you could see where the anodizing was worn down where the mag rubbed. Magpuls fall right out now. Not desirable to have to do this, but at least the mags fit now and I didn't have to track down the ever elusive shadow ops team.
